Among the renewable sources present solar energy is the most abundant form of resources that would not be
exhausted anytime soon. So to emulate the energy, solar cells convert sunlight into electricity which depends on solar insolation
level and temperature that lead to the variation of the maximum power point (MPP).
Herein, to improve photovoltaic (PV) system efficiency and increase the lifetime of the battery, a solar charge controller with
maximum power point tracker (MPPT) is designed for harvesting the maximum power available from the PV system under given
insolation and temperature conditions. Among different MPPT techniques, perturb and observe (P&O) technique gives excellent
results and thus is used in this project. The Perturb and Observe method is used to calculate the maximum power point and the
Boost converter is used for the step-up of the panel voltage. We have also simulated a flying capacitor multilevel inverter to
convert the DC supply into AC supply
